To all whom it may concern:

Be it' known that I, ALBERT"M. Am'x- ANDER, a citizen of theUnited Statesya'nd resident of Valley lWIills,-in 'the co unty of Bosque and State of Texas, ha-ve-inve'nted certain new and useful Improvements in F oot- A'ccelerators, of which the following is a specification- This invention relates to accelerators" espe'cially adapted for-use on automobiles".

An importan't object ofthe'invention is to providea-foot" accelerator which may bethe carbureter'witho'ut interfering with the handpperated throttle. 1

A further object of the invention is to provideafoot accelerator whichis of highly simplified construction, durable in use and cheap to manufacture.

Other, objects andaadvantages of the invention will be apparent dnringvthe course of the following description. a

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like partsthroughout the fsa'me,

Figure 1 is a perspective of the improved accelerator applied.

Figure 2 is a perspective of a bracket embodied in the invention.

Figure 3 is a perspective of a throttle operating rod embodied in the invention.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of the invention the numeral 5 designates a vehicle frame to which the engine 6 is bolted in the usual manner. As illustrated in Figure 1 the carbureter 8 is connected to the engine by means of the intake manifold 9 and is provided with a throttle arm 10 normally operated by the transversely extending link 11. The transversely extending link 11 which is connected to the throttle arm 10 is operated by means of the usual hand throttle arranged adjacent the steering wheel of the vehicle.

The invention forming the subject matter of this application includes a longitudinally movable arm 14 having its rear portion closed position.

curved longitudinally asindicate'd ,at 15 and terminating in an e'ar 16' apertured for.

The pedal 18. is in the nature of a longitudi nally movable-rodhav'ing its forward porv tion providedwith a'pair of spaced'parallel' ears 20 connected to theapertured ear 16' by means of the pivot element 17. I

As illustrated in Figure" 1 the movable the receptionof a pivotelement l'l-by means of which the arm is connected to a :pe'dalISJ-BO pedal 18 is slidable through the foot bo'ard 1 of-the' Vehicle andis -provided with a'diskshaped head 22 adapted to be depressed 'bythe foot when it is desired tofloper'ate 'the' throttle arm 10 of thecarbureterI A -suit able rest'2 maybe secured'to the foot board "of the motor vehicle adjacent the head 22 and may support a suitable portion of ones ifoot so that'the plunger or rod'18 maybe conveniently depressed.

The intermediate portion of the arm" liiis' I offset laterally as indicated at 25 and'the indicated at 26*for the receptionjof oneend tion-ary; portion of the x engine, and serves as a means for urgin the throttle valve to its H owever, when the :pedal is -..bend inthe offset portion is {apertured as l 8.80 of a. coiled'spring 27. The coiled I spring is connected at its rear end to a su table sta-' The forward portionof the arm-pro l videjd with ,a bend. 'defining a laterally v.projjecting attaching member 29 adapted for connection with the throttle arm of the carbureter. The arm rearwardly of the laterally projecting attaching member 29 is arranged in L-sha-ped formation to provide an upwardly extending branch 30 with a for wardly extending branch 31, which overhangs the carbureter.

The longitudinally curved arm 15 is slidable through the horizontally arranged loop of a bracket generally designated by the numeral 36, the said bracket being formed The spring 27 pulls rearwardly and is arranged directly be from a single length of metal having one end portion apertured as indicated at 37 for the reception of fastening devices whereby the bracket may be firmly secured to the frame of the vehicle or to any other convenient place. The intermediate portion of the length of metal from which the bracket is formed is provided with a clip 38 defining an upstanding arm 39 from which the elongated loop extends. As illustrated in Figure 2 is a pair of pulleys 40 are arranged within the loop and serve as a means for guiding the arm or curved portion. When the throttle arm 10 is moved about the axis of the butterfly a limited lateral movement of the arm 14 takes place and as the pulleys or guide rollers 10 are arranged in spaced relation this lateral movement of the arm is permitted.

In operation the pedal 18 is depressed for advancing the arm 14.- and this advancement of the arm results in the operation of the throttle 10. WVhen the pedal 18 is released the spring 27 promptly returns the arm 14 to its original position for cutting off the flow of fuel.

Also an accelerator constructed in accordance with this invention may be conveniently applied to'any vehicle without altering the construction of the same and by reason of the construction employed the parts are not easily rendered inoperative.

Having thus described the invention, what is claimed is v 1. A foot accelerator for motor vehicles comprising an arm having its forward portion provided with means whereby the same may be connected to the throttle arm of the carbureter, said arm being provided inter mediate its ends with an offset portion, a coiled spring connected to said offset portion and forming a means for retracting said arm, a longitudinally movable pedal pivotally connected to the rear portion of said arm, and a bracket having a loop and a pair of guide wheels contacting with the rear portion of said arm.

2. A foot accelerator for motor vehicles comprising an arm having its intermediate portion offset laterally and its forward portion arranged in L-shaped formation to provide upwardly and forwardly extending branches, the forwardly extending branch being adapted to overhang the throttle arm of the carbureter, said forwardly extending branch being provided with means whereby the same may be pivotally connected to the throttle arm of the carbureter, the rear portion of said arm being curved longitudinally and provided with an apertured ear, a longitudinally movable pedal slidable through the floor board of the vehicle and having its forward portion connected to the apertured ear of the arm and having its rear portion provided with a head adapted to be depressed by ones foot, a bracket formed from a length of metal having an attaching base and a horizontally arranged elongated loop, said loop being provided with a pair of spaced guide wheels between which the rear portion of said arm moves, and spring means connected to said arm for retracting the same.

3. A foot accelerator comprising an arm having its intermediate portion offset and its forward portion arranged in L-shaped formation to provide upwardly and forwardly extending branches, the forwardly extending branch being adapted to overhang the throttle arm of the carbureter, said forwardly extending branch being provided with means whereby the same may be pivotally connected to the throttle arm of the carbureter, the rear portion of said arm being curved longitudinally and provided with an apertured ear, and a longitudinally movable pedal slidable through the floor board of the vehicle and having its forward portion connected to the apertured ear.
